有无前列腺素类药物对眼压控制的原发性开角型青光眼患者24 h眼压的影响

目的 比较通过药物治疗眼压得到控制(峰压≤21 mm Hg)的原发性开角型青光眼(POAG)患者单用或联合应用前列腺素类(PGs)药物(有PGs组)和单用或联合应用其它降眼压药物(无PGs组)的24h眼压测量结果.方法 对经药物治疗后连续3个以上时间点测量的最高眼压值≤21 mm Hg的38例POAG患者(64只眼)于末次就诊的1周内进行24h眼压测量,对比分析有PGs组(20例31只眼)和无PGs组(18例33只眼)的测量结果(波动幅度、眼压峰值和平均眼压).结果 有PGs组和无PGs组的24h眼压波动幅度均值分别为(4.19±1.60)mm Hg、(5.63±1.71)mm Hg,差异有统计学意义(-3.479,P＜0.01);两组的眼压峰值均数分别为(17.81±1.68) mm Hg、(18.79±1.41)mm Hg,差异有统计学意义(t=-2.537,P＜0.05);有PGs组的平均眼压(15.89±1.68) mmHg低于无PGs组(15.96±1.53) mmHg,但差异无统计学意义(t=0.182,P＞0.05).结论 通过药物治疗眼压得到控制的POAG患者中,尽管两组24h眼压测量的平均眼压没有差别,但有PGs组的波动值和眼压峰值均低于无PGs组,提示PGs比其他药物对24h眼压的控制效果更好.     

24小时眼压监测中夜间眼压测量方法的探讨

目的比较24h眼压监测中夜间即刻坐位眼压值和坐起休息10min后测得的眼压值,探讨夜间眼压的不同测量方法对青光眼24h眼压昼夜波动的影响。方法对已确诊且未用药、未做过手术的48例正常眼压性青光眼及17例原发性开角型青光眼患者进行24h眼压监测,每2h1次,其中测量夜间0:00、2:00、4:00眼压时,逐个唤起患者后立即测,后嘱患者坐起休息10min再测,采用SPSS软件以配对t检验分析比较测量结果。结果夜间即刻坐位眼压值和坐起休息10min后测得的眼压值差异有统计学意义(P<0.001),正常眼压性青光眼与原发性开角型青光眼间眼压差值差异有统计学意义(P<0.05)。结论即刻坐位眼压值能更准确反映夜间眼压,对24h眼压测量及青光眼诊断及治疗更有价值,值得临床应用。

高眼压症及原发性开角型青光眼患者的24 h眼压波动规律

目的 通过24 h眼压测量来深入分析对比高眼压症与原发性开角型青光眼(POAG)患者的眼压曲线特征。方法 收集2016年1月~2019年3月在我科门诊诊断为高眼压症的患者52例(104眼)及POAG尚未接受降眼压治疗的患者38例(76眼)。入院后行24 h眼压检查,用非接触性眼压计从早9时起每隔2 h测量眼压1次,至次日7时结束。分析2组患者的平均眼压,峰值眼压及时间点,谷值眼压及时间点,昼夜眼压波动及双眼眼压压差值及其分布情况,比较2组眼压波动的异同点。结果 104眼高眼压症患者的平均眼压为(18.73±1.71)mmHg(1 mmHg=0.133 kPa),平均峰值眼压为(22.36±2.40) mmHg,平均谷值眼压为(15.63±2.09) mmHg,平均昼夜眼压波动为(6.72±2.24) mmHg。76眼POAG患者的平均眼压为(20.65±2.53) mmHg,平均峰值眼压为(25.78±2.81) mmHg,平均谷值眼压为(17.45±2.54) mmHg,平均昼夜眼压波动为(8.34±2.37) mmHg。2组的峰值及谷值眼压值分布最多的时间点均为凌晨3时及夜晚21时,大部分患者的峰值眼压时间点在门诊时间之外。高眼压症组中昼夜眼压波动位于5~8 mmHg的占比最大,为54.81%(57/104),POAG组中昼夜眼压波动>8 mmHg的占比最大,为53.95%(41/76)。高眼压症组中,16例患者经24 h眼压检查后监测到眼压波动异常,占比为30.77%(16/52);POAG组中经24 h眼压检查后有29例患者可以监测到眼压波动异常,占比为76.32%(29/38)。结论 24 h眼压监测中,POAG患者较高眼压症患者的平均眼压、峰值眼压、谷值眼压、昼夜眼压波动及双眼压差均有增加。对于24 h眼压发现眼压波动较大的高眼压症患者应在后续加强密切随访,而对于POAG患者24 h眼压监测可在治疗前提供眼压的基线水平,为后续治疗提供参考及评估依据,因此建议将24 h眼压作为高眼压症及POAG的常规检查手段。     

同步监测青光眼患者24h眼压与血压的意义

青光眼是世界范围内致盲和引起视力损害的主要眼病,也是不可逆性致盲性眼病之一.眼压是青光眼发生发展的重要危险因素,但除眼压外,血压在青光眼进展引起的影响也不可忽视.眼灌注压是血压和眼压的差值,可调节视神经的血液供应.眼压、血压、灌注压在青光眼发生发展中有一定相关性.本文通过对眼压和血压在青光眼中的影响以及24 h眼压和血...     

Relation between office intraocular pressure and 24-hour intraocular pressure in patients with primary open-angle glaucoma treated with a combination of topical antiglaucoma eye drops

PURPOSE: To determine the relation between office intraocular pressure (IOP) and 24-hour IOP in patients with primary open-angle glaucoma (POAG) treated with 3 kinds of antiglaucoma eye drops. PATIENTS AND METHODS: Subjects were 42 patients with POAG (71 eyes). All were being treated with 3 different topical antiglaucoma eye drops (latanoprost, beta-blocker, and carbonic anhydrase inhibitor). Twenty-four-hour IOP values were obtained in the sitting position with a Goldmann applanation tonometer at 3-hour intervals. RESULTS: Maximum 24-hour IOP (mean+/-SD) was 19.76+/-5.65 mm Hg, minimum 24-hour IOP was 13.06+/-4.75 mm Hg, mean 24-hour IOP was 16.30+/-4.90 mm Hg, and 24-hour IOP fluctuation was 6.70+/-2.81 mm Hg. Office IOP was 16.23+/-4.58 mm Hg, and office IOP fluctuation was 2.75+/-1.68 mm Hg. There was no significant difference between office IOP and mean 24-hour IOP (P=0.93). There was no correlation between office IOP and 24-hour IOP fluctuation (r=0.15; P=0.25) or between office IOP fluctuation and 24-hour IOP fluctuation (r=0.19; P=0.17). Maximum 24-hour IOP occurred during office hours in 22 eyes (33.8%). The frequency of maximum 24-hour IOP occurring during office hours was significantly less than that of minimum 24-hour IOP (P<0.001). CONCLUSIONS: In POAG patients treated with 3 kinds of antiglaucoma eye drops, office IOP was similar to mean 24-hour IOP. However, it was difficult to estimate 24-hour IOP fluctuation and maximum 24-hour IOP on the basis of office IOP.

测量间隔时间对24 h眼压波动的影响

目的 观察青光眼和疑似青光眼患者24 h眼压波动规律及不同测量间隔时间对其的影响.方法 选择疑似及确诊青光眼患者60例(120眼),进行24 h眼压测量.所有患者上午8:00至晚上23:00,每1h测量一次眼压,晚上23:00至第2天早上7:00每2 h测量一次,共20次.结果 68眼(56.7%)眼压异常.眼压低谷出现在晚上19:00至23:00(52眼,43.3%),平均眼压为(16.17±5.56)mmHg(1 kPa=7.5 mmHg);高峰出现在上午9:00至11:00(41眼,34.2%)和第2天凌晨1:00至5:00(42眼,35.O%),平均眼压分别为(18.28±5.27)mmHg和(17.95 4±6.40)mmHg.按间隔时间1 h、2 h、3 h、4 h对测量数据统计,其阳性率分别为45.8%、35.8%、27.5%、21.7%;而阴性率分别为5.8%、16.7%、25.8%、49.4%.结论 青光眼及疑似青光眼患者的眼压高峰不但出现在上午也出现在凌晨睡眠时间.为更好地观察患者眼压的波动情况,应尽量缩短24 h眼压测量的间隔时间.
